What to do with tall oak and ash trees

[mazdaq]

We have loads of tall, spindly trees in our garden - mainly oak, ash and cherry. I felled quite a few when we first moved in several years ago but have noticed that the remaining ones have really started to impact on sunlight in our garden and house this year. Wondering what to do with them.

 

A few pictures attached of the main ones blocking the sun in the late afternoon/evening.

 

Many of them are around 30m tall. Ideally, I'd like to significantly reduce the height of them (maybe by half) but I've no idea what would happen to them - would they forever look like telegraph poles or would they gradually grow a new canopy at the new height?

 

Or do I fell a few more of them and thin out the canopy of the remaining ones?

 

Any advice/ideas much appreciated.

Second picture shows some canopy die back if ash fell them rather than anything else.

I wouldn't consider reducing the height of those. I'd thin them and leave a few of the best ones. 

 

Pictures must be deceiving, none look anywhere near 30m tall.
